TO LEO A. BRIGEL, J R., AND EDWARD J. BRIGEL, TRADING UNDER FIRM- NAMEOF CINCINNATI PUMP COMPANY, OF CINCINNATI, OHIO.

CHAIN-PU MP.

SPECIFICATION forming part bf Letters Patent No. 700,729, dated May 27,1902.

Application filed September 17,1898. Serial No. 691,275. (No model.)

To all whmn it may concern.-

Be it known that I, LEO A.'BRIGEL, a citizen of the UnitedStates,'residing at Cincinnati, in the county of Hamilton and State ofOhio, have invented certainnew and useful Improvements in Chain-Pumps,of which the following is a specification.

My invention relates to certain improvements in chain-pumps, and moreparticularly to in the tubes and reservoirs used in pumps of this class;and the object of my invention is to simplify and cheapen theconstruction of such parts, while at the same time making them strongand durable. My invention consists in certain novel features of theconstruction, combination, and arrangement of the tube and reservoirwhereby certain important advantages are attained, and the device ismade simpler, cheaper, and

otherwise better adapted and more convenient for use, all as will behereinafter fully set forth. 7

The novel features of my invention will be carefully defined in theclaim.

In order that my improvements may be the better understood,'I have shownin the accompanying drawings a tube and reservoir constructed accordingto my invention, in which drawings- Figure 1 is a side elevation showingthe tube and reservoir attachedthereto, parts of the tube being brokenaway for lack of space. Fig. 2 is an enlarged transverse section takenthrough a curb having a curved wall and showing myimproved reservoir inplace therein. Fig. 3 is an enlarged section taken axially 5 through thereservoir and tube and showing the means for securing these partstogether- Fig. 4: is an enlarged detail bottom view show- 40 ing theform of the bottom plate of the reservoir before it is secured thereto.Fig. 5 is an enlarged transverse section taken through the tube andshowing a button in place in the same. Fig. 6 is a sectional viewsimilar to Fig. 2, but showing the arrangement of the improved reservoirin a curb having a straight or flat wall.

As shown in the views, the tube is formed in sections 1 and 2, connectedby means of coupling 3 ma well-known way and is provided at its lowerendwith a flared or funnelshap'ed'mouth 4, adapted to facilitate the entryof the buttons into the tube and also serving to protect said lower endof the tube from being excessively worn by the chain.

5 indicates the reservoir, made in elongated form from sheet metal, thecorners of said reservoir being beveled or flattened, as shown at 6, soas to give it an octagonal form in cross-section. The edges of the metalsheet of which the reservoir is formed are doubleseamed together alongthe back of the reservoir, as shown at 7 in the drawings.

8 indicates the bottom of the reservoir, also made from sheet metal andhaving its outer edges flanged, as shown in Fig. 4, said flange beingnotched at each corner to permit it to be bent and double-seamed" to thelower edges of the reservoir 5, as clearlyshown at 9 in the sectionalview, Fig. 3, and said bottom plate S is alsoformed with a centralcircular opening adapted for the passage of the upper end of the uppersection 2 of the tube, around which opening is formed a dependingintegral flange or lip 10, adapted to fit closely to the sides of thetube. 3

The tube is formed from sheet metal bent to a circular form incross-section and having its edges preferably united by flanging anddouble-seaming to produce a rib 11, extend- 8o ing longitudinally downthe outside of the tube at one side, which ribll is received in a socket12, formed within'the flange 10 at one side of the opening in the bottomof the reservoir when the latter is secured to the tube.

On theoutside of the tube diametrically opposite to therib 11 isproduced another outwardly-projecting longitudinal rib 13, formed bypressing or bending out the side of the tube from the arc of a truecircle, and said rib o 13 is adapted to be received in a socket 14,formed within the flange 10 at the side of the opening in the bottom 8of the reservoir opposite to the socket 12.

In order to secure the reservoir to the tube, 5 the end of the latter ispassed through the opening in the reservoir-bottom, after which a flange15 is formed on the tube within the reservoir by expanding the insertedend of the tube, so as to prevent the withdrawal of the same from theopening. Solder is also applied around the lower edge of the flange 10,so as to hold the tube and reservoir firmly together. These parts mayalso be secured together by turning the flange 1O upwardly within thereservoir (instead of downwardly on the outside thereof, as shown inFig. 3) and double-seaming it with flange 15, in which case I prefer topress the parts together, so that the flange 15 will be fitted into adepression in the bottom formed around the central opening thereof,making said flange flush with the interior exposed surface of the bottom8 of the reservoir. When so constructed, the solder may be entirelyomitted.

A channel 16 is formed within the tube by the bending of the wall of thelatter to form the rib 13, and said channel extends longitudinallythrough the tube and is adapted to allow the water held in the reservoirand in the upper part of the tube to flow past the buttons (indicated at17 in Fig. 5) down into the cistern after the chain ceases to move, soas to prevent the water from freezing in the tubes and reservoir in coldweather and also from becoming stagnant in warm weather, as will bereadily understood. y

In Fig. 2 I have shown the reservoir applied to a curb made from sheetmetal and having a curved end wall 18, outside which is arranged acasting 19, having a spout 20, one end 21 of which passes through anopening in the curb and also through an opening 22, cut in the frontface of the reservoir 5, as clearly shown in Fig. 1. The opposite sidesof the casting 19, which is curved to fit flush on the outside of thecurb, are perforated for the passage of the ends 23 of a yoke or stirrupbent from a bar or rod of metal. Said ends are screw-threaded to receivenuts 24: outside the curb, and the central part 25 of the stirrup isarranged to fit in a transverse crease or recess 26, formed inthe backof the reservoir opposite the opening 22, so that when said nuts 24 arescrewed home the reservoir will be clamped tightly in place within thecurb.

By makingthe reservoir with flattened front face and beveled corners thesame is given secure bearing against the inner surface of the curb,since said construction provides two points of engagement between theparts extending the full length of the reservoir at each side of saidflattened front surface, and said construction also permits thereservoir to be used in a curb having a fiat end wall,

as shown at 27 in Fig. 6, the flattened front side of the reservoirresting in this case directly against the fiat inner surface of thecurb-Wall 27.

28 indicates the casting,formed to fit against the outside of thecurb-wall and having a spout 29, one end 30 of which passes through anopening in the curb-wall and also through an opening in the front sideof the reservoir, as above set forth. The reservoir in this case is heldin place by means of a stirrup like the one above described.

In mounting the reservoir and tube Within the curb the parts are soarranged that both the ribs 1l and 13 on the pump-tube are in the planein which the strain of the chain moving over its wheels is exerted, sothat both of said ribs act to impart strength to the tube to enable itto resist such strain. In this way a considerable economy in the use ofmetal is effected, since it is rendered possible to use metal of muchless gage than would or stopped up, but is kept open and clear frombottom to top by pressure of the buttons sweeping along its entirelength. It will also be obvious from the above description that myimproved tube and reservoir is capable of some modification withoutmaterial departure from the scope and spirit of myinvention, and forthis reason I do not wish to be understood as limiting myself to theprecise form and arrangement of the parts herein set forth.

Having thus described my invention, I claim- A tube havinga longitudinalseam extending along one side and forming an exterior strengthening-rib,and having at its opposite side an outwardly-bent portion forming alongitudinal strengthening-rib outside the tube and also forming insidethe tube a longitudinal channel, substantially as set forth.
